Our Abpromise guarantee covers the use of ab28761 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 100 kDa (predicted molecular weight: 100 kDa).Can be blocked with PDE5A peptide (864-875) (ab45684).


  • FunctionPlays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP.
  • Tissue specificityExpressed in aortic smooth muscle cells, heart, placenta, skeletal muscle and pancreas and, to a much lesser extent, in brain, liver and lung.
  • PathwayPurine metabolism; 3',5'-cyclic GMP degradation; GMP from 3',5'-cyclic GMP: step 1/1.
  • Sequence similaritiesBelongs to the cyclic nucleotide phosphodiesterase family.
    Contains 2 GAF domains.
  • DomainComposed of a C-terminal catalytic domain containing two putative divalent metal sites and an N-terminal regulatory domain which contains two homologous allosteric cGMP-binding regions, A and B.
  • Post-translational
    Phosphorylation is regulated by binding of cGMP to the two allosteric sites.
